The Governance Context formed through Umecohming may include not only information that can be made public, but also information intended for internal organizational use. When content is published externally, it is therefore necessary to control which elements of Governance Context are disclosed and which remain internal. In I2EA, this boundary is defined as the Publishing Boundary.

Within an organization, information such as Confidential, Internal Use Only, and Under Internal Review may be necessary for Decision-making and audit purposes while remaining inappropriate for external disclosure. At the same time, published content may require information such as License, Attribution, Usage Policy, and Provenance for external users and systems.

The Publishing Boundary receives the content and its Governance Context as Input and determines, based on Applicable Policy, Authority, and Disclosure Requirements, which information should be disclosed, transformed, or retained internally. This is not merely the removal of metadata. Rather, publication itself is treated as a governance Decision.

Internally, data, metadata, applicable Policies, Decision history, and related information can be retained as Decision-State Evidence (DSE). This makes it possible to verify later what information was disclosed and what was excluded, even when only a limited subset is released externally.

Externally, rather than exposing the complete internal DSE, a Public Evidence Record can provide the necessary Public Metadata and Decision Record. This allows Provenance, conditions of use, and information supporting the publication Decision to remain verifiable without unnecessarily exposing internal information.

Accordingly, the Publishing Boundary is a mechanism for managing the boundary between internal and external Governance Context and determining, based on Policy and Authority, what is disclosed, what is transformed, and what remains internal.

Maintaining Governance Context and disclosing Governance Context are separate governance questions. The Publishing Boundary clearly separates the two.
